It's an interesting thing to contemplate. I would think if a vampire was bit it would only hinder him, because zombies are undead, but they still rot, then again most vampires have rejuvenation powers, as do werewolves. Still, they would still have to feed their constant desire for flesh, a hard thing to do when you have to sleep in the daytime.

A werewolf/zombie hybrid would be awesome, especially if the only thing that would kill it is a silver bullet to the brain, which of course using movie logic, would take a long time to figure out.

A zombie/werewolf/vampire would be overkill, but cool. As long as this combination somehow mutated in order to go out during the day.

Now, imagine a zombie kaiju! Or a zombie Xenomorph! Or a zombie Predator for that matter!

What about other animals becoming zombies? The monster in "Mammoth" was much like a zombie woolly mammoth, so what about a zombie hippo or a zombie polar bear? Insects that carry the zombie plague? How about a horde of zombie army ants?

Have any of you guys read the Marvel Zombies comics? It's a story about what happens when various Marvel heroes become infected with Zombism. Check it out if you want to see a Zombie Wolverine, Zombie Spidey or Zombie Hulk etc.
